The T(¹H, γ)⁴He reaction has been studied for the first time in the energy range E_lab = 12–34 keV in the laboratory coordinate system (E = 7.8–20.1 keV in the center-of-mass system). The study of this reaction is of interest because it is involved in the primary nucleosynthesis of ⁴He and is important for the theory of few-nucleon systems. The reported experiment improves the accuracy of the experimental determination of the S-factor of the T(¹H, γ)⁴He reaction by several times. The theoretical calculations of the S-factor of the T(¹H, γ)⁴He reaction still differ from the experimental values by a factor of about 2.

天体能量下T（1 H，γ）4 He反应的S因子的测量

T（¹ H，γ）⁴ He反应已在实验室坐标系中的能量范围E _lab = 12–34 keV中进行了首次研究（质心系统中的E = 7.8–20.1 keV） 。该反应的研究很有趣，因为它参与了⁴ He的初次核合成，并且对少数核子系统的理论很重要。报道的实验将T（¹ H，γ）⁴ He反应的S因子的实验测定精度提高了数倍。T（¹ H，γ）⁴的S因子的理论计算他的反应仍然与实验值相差约2倍。
